Figure 6From: Interpreting finite element results for brittle materials in endodontic restorations Normal stress in the x-direction for DTT for the exterior diameter defined by z = t/2, x = 0. Normal stress in the x-direction, σ x , along the line defined by z = t/2, x = 0, y = [0, D/2] for the six DTT models with thicknesses from 1 mm to 6 mm, and the theoretical result obtained with the plane stress hypothesis.Back to article page
